A total of 96 Shaver 579 laying hens of 78 weeks of age were studied for the effects on egg production of dietary supplementation with spirulina (Spirulina platensis). The hens were divided into four dietary treatments with six replications of four birds in each group. Birds of three groups were supplemented with 0.1%, 0.2% and 0.3% spirulina and one group was kept as control. Yolk colour significantly improved (P<0.01) as compared to control, without affecting any other production performances. It is suggested that dietary supplementation of spirulina at 0.2 to 0.3% levels in aged laying hens enhanced egg yolk colour. Bangl. vet. 2017. Vol. 34, No. 2, 71-78

The present study evaluated the effects of dietary supplementation of chitooligosaccharide (COS) on egg production, egg quality and blood profiles in laying hens. A total of 192 Hy-Line Brown laying hens (initial age- 46 weeks) were allocated to one of four treatments with eight replications per treatment and six adjacent cages as replication for eight-weeks study. Dietary treatments consisted of CON, basal diet; COS1, CON + 0.1% COS; COS2, CON + 0.2% COS; and COS3, CON + 0.3% COS. Linear improvement (p Lass Than 0.05) was observed in egg quality and high-density lipoprotein cholesterol (HDL/C) concentration at subsequent weeks. In week 8, linear (P=0.04) improvement was observed in haugh unit of egg with the increase in the dose of COS. In addition, linear effects (p Lass Than 0.05) on eggshell thickness at week 3, 5, 6, 7 and 8 were detected as the level for increased COS. In conclusion, the supplementation of COS in laying hens diets linearly improved the egg quality and the HDL/C concentration. Thus, COS has the potential to be used as a substitute to antibiotics in layer hen’s diets.

Two experiments were conducted to evaluate the effect of including protected sodium butyrate (PSB) in the diets of laying hens of advanced age on productive performance and egg quality. In experiment 1, a total of 320 Dekalb White 61-week-old laying hens were distributed in a randomized block design to four treatments (0, 105, 210, and 300 g/ton of PSB) with eight replicates of 10 birds. The experiment was conducted over 112 days, divided into four periods of 28 days each. Productive performance and egg quality were evaluated. In experiment 2, a total of 58 000 Dekalb White 70-week-old laying hens were assigned to diets containing either 0 or 105 g/ton of PSB with two replicates of 14 500 birds. The experiment was conducted on a commercial poultry farm. Egg production and the percentages of broken eggs and dirty eggs were evaluated. The PSB levels did not influence the productive performance of laying hens. A quadratic effect was observed for eggshell thickness, percentage of eggshell and eggshell strength, reaching maxima at 193, 136 and 198 g/ton of PSB, respectively. A quadratic effect on yolk index reached a minimum at 181 g/ton of PSB. The percentages of dirty eggs and broken eggs were lower in laying hens fed 105 g/ton of PSB. In conclusion, the addition of PSB to the diets of old laying hens improved the eggshell quality and decreased the percentage of broken and dirty eggs Keywords: egg quality, laying hens, organic acids, performance, protected sodium butyrate

The aim of this study was to evaluate the influence of the dietary addition of sodium humate (HAS) on performance and immune response of laying hens during peak lay, over an eight-week period. Laying hens, aged 24 weeks old, were randomly allotted to four dietary treatments: a basal control diet or the basal diet supplemented with 0.1, 0.3 or 0.5% HAS. Each treatment had six replicates with 15 layers per replicate. Egg production, egg quality, serum antioxidant parameters and immunity indexes were measured. HAS had no significant effect on egg production or egg and shell quality, but all supplemental levels significantly improved Haugh unit values and egg yolk colour. Supplementation with all levels of HAS significantly increased serum immunoglobuline (Ig) level compared to the hens fed the control diet. Feeding either 0.1 or 0.5% HAS significantly increased serum IgM levels. The results indicated that dietary supplementation with HAS can enhance egg albumin quality and improve immunity in laying hens.

Vitamin C Supplementation

Abstract Endogenous synthesis of vitamin C may satisfy its requirement for laying hens; however, some previous experiments showed beneficial effects of dietary supplementation of vitamin C in laying hens. Thus, the results are still controversial. The objective of the current experiment, therefore, was to investigate the effect of vitamin C supplementation in diets on productive performance, egg quality, relative organ weight, and tibia strength in laying hens. A total of 504 46-wk-old Hy-Line Brown laying hens were allotted to 1 of 6 dietary treatments with 7 replicates in a completely randomized design. Each replicate had 12 hens. Diets were prepared by supplementing the basal diet with vitamin C at the levels of 250, 500, 1,000, 2,000, or 3,000 mg/kg and were fed to hens for 6 wks. Results indicated that increasing supplementation of vitamin C in diets increased hen-day egg production and egg mass (quadratic, P &lt; 0.05), but decreased production of broken or soft-shell eggs (linear and quadratic, P &lt; 0.01) and feed conversion ratio (quadratic, P &lt; 0.05). These positive effects were observable at the supplementation level of 250 mg/kg vitamin C, but there were no further benefits at the greater levels of vitamin C. Increasing supplementation of vitamin C in diets had no effects on egg quality, except for a decrease (quadratic, P &lt; 0.01) in egg yolk color with increasing vitamin C supplementation. The relative weights of the liver, kidney, and spleen were not affected by increasing supplementation of vitamin C in diets. Tibia strength was not influenced by increasing supplementation of vitamin C. In conclusion, dietary supplementation of vitamin C has a beneficial effect on egg production of laying hens. Quadratic responses of increasing vitamin C supplementation in diets reveal that supplementation of 250 mg/kg vitamin C is recommended for diets fed to laying hens at 46–52 wks of age.

Laying Performance

This study aimed to investigate the supplemental effects of fermented pine (Pinus densiflora) needle extract (FPNE) in laying hen diets on productive performance, egg quality, and serum lipid metabolites. A total of 108 40-week-old Hy-line brown laying hens were randomly assigned to one of the three dietary treatment groups: (1) basal diet + 0 mL FPNE/kg diet (CON), (2) basal diet + 2.5 mL FPNE/kg diet (T1), or (3) basal diet + 5 mL FPNE/kg diet (T2) for 6 weeks. Each group consisted of four replicates of nine hens each. Feed and water provided ad libitum. Results showed that dietary supplementation of FPNE increased egg production percentage (linear, p < 0.01 and quadratic, p < 0.05), egg mass (linear, p < 0.05), and feed intake (linear, p < 0.05) during the entire experimental period. In addition, dietary inclusion of FPNE significantly increased the eggshell color (linear, p < 0.01), egg yolk color (quadratic, p < 0.01), and eggshell breaking strength (linear, p < 0.05 and quadratic, p < 0.05) while the Haugh unit decreased (quadratic, p < 0.05). However, serum lipid profile did not differ among the dietary treatments (p > 0.05). Notably, antioxidant activity of egg yolk was improved by significantly decreasing the malondialdehyde content in egg yolks after 6 weeks of storage (linear, p < 0.001 and quadratic, p < 0.05). In summary, dietary inclusion of FPNE could improve laying performance and the antioxidant capacity of eggs.
